avfilter API requires all the filter parameters, including hw context
(if present) to be available during init, so that is the proper place to
perform such setup.
The "progress2" API in pthread_slice.c currently associates a progress
value with a thread rather than a job, relying on the broken assumption
that a job's thread number is equal to its job number modulo thread
count.
This removes this API entirely, and changes hevcdec to use a
ThreadProgress-based implementation that associates a
mutex/cond/progress value with every job.
Fixes races and deadlocks in hevdec with slice threading, e.g. some of
those mentioned in #11221.
While we only add the flag if the linker seems to support it,
it turns out that ld.bfd had a bug where the flag is accidentally
accepted, and the flag produces an output file named
"_warn_duplicate_libraries".
The ld.bfd bug was fixed in binutils 2.36, in
https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=3991c7acb29aa8d7d52150695eb3efa03a08dd50.

FATE results differ when using the original zlib and zlib-ng.
Since we don't need to test the result from zlib itself, this commit
disables compression on tests for zlib-based codecs, which ends up
giving the same results with both libraries.

md5 values change because the nut container now reports rawvideo as encoder
and Y410 as codec type instead of the bogus RGB[15].

The documentation of av_fourcc_make_string states the passed in
buffer must be of at least the size of AV_FOURCC_MAX_STRING_SIZE .
Using av_fourcc2str uses the correct buffer size and moves the
buffer into a nested scope while also being shorter.

If 'sname:*' is set in the var_stream_map variable, use it as
the NAME attribute for subtitles. This improves the naming of
subtitle streams in HTML players, providing clearer and more
descriptive labels for users.

Ensure that when the `-hls_flags omit_endlist` option is set,
the `#EXT-X-ENDLIST` tag is also omitted from the `stream_vtt.m3u8`
subtitle playlist. This maintains consistency with the behavior
in other playlists when `omit_endlist` is specified.

Ensure that when the `-hls_flags append_list` option is set,
that *.vtt files in stream_vtt.m3u8 are correctly updated.

Note1: when the EOF pts is not accurate enough, the last frame
can be dropped by vf_fps with default rounding.
Note2: vf_scale use framesync since e82a3997cd,
so this is a very commonplace scenario.
For example:
./ffprobe -f lavfi testsrc=d=1,scale,fps -of flat \
-count_frames -show_entries stream=nb_read_frames
Before:
streams.stream.0.nb_read_frames="24"
After:
streams.stream.0.nb_read_frames="25"

When displaying help for overlay filter in CLI, the flags for x and y
parameters don't have the T flag. However these two parameters do have
the capability to be set at runtime, as implemented in commit
d2752ef061. This commit fixes the CLI documentation.

This is unreachable anyway so performance is not an issue here. Allows
guiding the compiler in all build modes to not emit a spurious warning
here:
warning: variable 'mag' is used uninitialized whenever switch default is taken
